That is a problem with libtool picking up the 32bit development library if the
net-snmp-devel i386 package has been installed.
To resolve this problem remove the net-snmp-devel.i386 package using:
rpm -e net-snmp-devel.i386
on a command line.

The problem is that libtool never was really properly designed to be used for
development on multilib platforms.
So fixing it would probably require quite a bit of work how libtool selects and
finds libraries for those cases.
Additionally, most packages come with their own copy of libtool in order to have
a know working one with that specific package, so fixing libtool itself might
work for some packages that use the system libtool but not for quite a few others.
